MILK-STRAlNER.

SPECIFICATION forming part of Letters Patent No. 549,276, dated November 5, 1895. Application ned rebmryz, 1895. serial 110,539,576. (remodel.)

To all whom, t may concer-7e:

Be it known that I, PHILIP PFEIL, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Milk-Strainers, of which the following is a full, clear, and eX- act description, reference being had to the ac-v companying drawings, forming a part hereof.

My invention has relation to improvements in detachable strainers and it consists in the novel arrangement and combinationof parts Inore fully set forth in the specification and pointed out in the claims. y

In the drawings, Figure V1 is a perspective view of my improved strainer as attached to a milk-pail spout, and Fig. 2 is a middle vertical longitudinal section of the strainer on the line 03 c of Fig. 1.

The object of my invention is to construct a strainer adapted to be readily attached to and detached from the pouringspout of milkpails and, when once attached, to insure a tight joint between the spout and strainer, without necessitating the formation of grooves or recesses for the reception of one edge of the strainer, which recesses in ordinary pails serve to accumulate the impurities floating on top of the millggiving rise vto bad odors and possible fermentation and making it tedious to clean the groove. By my construction all such objections are avoided.

In detail the invention may be described as follows:

Referring to the drawings, 1 represents the spout of an ordinary milk-pail, the spout being outwardly convex, as usual, and the pail,

as well as the spout7 being provided along the upper edge with a wire band 3, located about the outer surface of the pail, the free edge of the pail being folded over the wire, as shown in Fig. 2. By this construction the inner surface of the pail and spout is left perfectly smooth, allowing the contents of the pail to flow uninterruptedly until it reaches the strainer. The strainer is composed ofa suitable plate 4, havingarear transverse edge 5 and a curved edge bounded by an upturned wall 6 and conforming in outline to the general curvature of the upper convex edgeof the spout. An opening is cut in the plate 11, over which the strainer-'gauze 7 issuperposed,

joint between it and the'spout.

Pivoted to the plate 4f, preferably midway between the opposite ends ofy the rear edge 5 `thereof and adjacent to said edge, isa lockingarm'10,of a length tofspan the fullwidth of'the strainer and having a terminal hook 11, adapted lto sweep about `theourved edge of the strainer, and embrace and firmly seize the wire band 3 at the'point of. extreme conveXity of the spout, thus firmly securing the strainer to the spout, as shown in full lines in Fig. 1,(the dotted position of the arm and hook showing the disengaged position of these parts.) The rear of the strainer is held by the lateral retaining-lugs 12, each having an upturned end or toe 13,adapted to pass under the wire band 3. Inasmuch as the strainer is secured to the spout by passing the plate 3, with its lugs 12, from the front of the spout rearwardly until the lugs meet the sides of the spout, it is apparent that even with pails whose spouts may vary slightly in width at their meeting portions with the pail the present form of strainer can always be forced along the spout until the toes of the lugs 12 are in engagement with the lower edge of the wire band 3, when the forward portion of the strainer can be secured by the hook 12, as already explained.

With my improvement the wire band 3 of the upper edge of the pail can be disposed along the outer surface, leaving the inner surface of the pail perfectly uninterrupted and smooth, there being no depressions or grooves formed for the reception of the curved edge of the strainer, which are liable to hold sediment and within which are liable to lodge matters conducive to the generation of lactic. fermentation. The pail can always be kept perfectly clean and the joint between the wall 6 and flange 9 and the upper edge of the pail is perfectly tight.

Having described my invention, what I claim is- Y i 1. .A milk strainer adapted to be secured IOOl to the outer terminal wire of a pail and its spout, comprising a suitable plate having a rear transverse edge, a curved forward edge, adepending lug at the opposite ends of the transverse edge, each lu g havin g a toe adapted to pass under the wire along the outside surface of the pail, a curved wall and an out Wardly extending ange following the curved forward edge, the said fiange being` adapted to rest alon g the curved edge of the spout, and the wall being adapted to rest against the smooth inner surface of the spout, an arm pivoted to the plate between the opposite ends of the transverse edge and adjacent to said edge, and a terminal hook on said arm adapted to sweep about the entire curved edge of the strainer and seize the wire secured to the upper edge of the pail, substantially as set forth.

2. In a milk strainer adapted to be secured zo to the outer terminal wire of a pail, and its spout, a suitable plate having' a rear transverse edge, a curved forward edge, a rigid depending lug at the opposite ends of the transverse edge, each lug havin g a toe adapted to pass under the wire on the outside of the pail at the juncture of the pail with the spout proper, and a locking arm pivoted to the plate having a hook adapted to lock the plate at the forward end by seizing the wire on the outside of the pail, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
